Rosa hybrida shrub named &#39;AUSKINDLING&#39;

ABSTRACT

A variety of rose plant of the shrub class, named ‘AUSkindling’. The ‘AUSkindling’ is a variety of a rose with a long flowering season, and pretty peachy pink buds that open to reveal pure white chalice-shaped blooms. The blooms maintain their shape during wet weather and have a moderate old rose fragrance.

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims priority to European CPVO 2015/2229,filed Sep. 24, 2015.

Classification: The present invention relates to a new Rosa hybridashrub of the market class ‘English Rose’.

Variety denomination: The new plant has the varietal denomination‘AUSkindling’.

ORIGIN OF INVENTION

This Invention relates to a new and distinct variety of shrub rose plantnamed ‘AUSkindling’, which was originated from the cross-pollination ofthe two ‘unnamed’ and unpatented seedlings of Rosa hybrida.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a rose varietywith a long flowering season, and having peachy buds that open to purewhite, chalice-shaped blooms with a moderate old rose fragrance.

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from otherspresently available and commercial rose cultivars known to the inventoris the following combination of characteristics: blooms having petalswhite in color that are chalice-shaped; a moderate old rose fragrance;having a long flowering season; and healthy shrubbery.

Asexual reproduction of the new variety by budding as performed atBowling Green Lane in Albrighton, Britain shows that the foregoing andother distinguishing characteristics come true to form and areestablished and transmitted through succeeding asexual propagations.‘AUSkindling’ may be asexually propagated by budding. The buddingsuccessfully occurred on the plant/rootstock Rosa dumetorum ‘Laxa’ forthe observed plants.

COMPARISON WITH PARENTS

The maternal and paternal parents of ‘AUSkindling’ are two unnamedseedlings. The new rose may be distinguished from its maternal parent,by the following combination of characteristics: the maternal parent isa shrub with a yellow flower. The new rose may be distinguished from itspollen parent, by the following combination of characteristics: thepaternal parent has a climbing growth habit with an apricot-pink flower.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is the‘AUSprior’ (U.S. Plant Pat. No. 19,465). Although both roses are white,the new rose may be distinguished from the ‘AUSprior’ roses that have aslightly yellow hue (RHS 155B (white group)) whereas the ‘AUSkindling’roses that have a slightly pink hue (RHS N155D (white group)). Theblooms of ‘AUSprior’ are also cupped with approximately 121 petals,whereas ‘AUSkindling’ is a similar sized bloom but with a more open cupwith around 52 petals. The ‘AUSprior’ has buds which are RHS 1D(green-yellow group) when the sepals first divide, whereas for‘AUSkindling,’ the buds first show RHS N155B (white group). Finally,‘AUSprior’ has an arching, lax growth whereas ‘AUSkindling’ has astrong, broad open growth.’

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows theflowering thereof from bud to full bloom depicted in color as nearlycorrect as it is possible to make in a color illustration of thecharacter. Throughout this specification, color references and/or valuesare based upon the Colour Chart of The Royal Horticultural Society(2001) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY
